### Abstract

This paper obtains the traveling wave solution to a nonlinearly coupled wave equation. Subsequently, the mapping method and its extended and modi ed versions are also employed to obtain additional solutions to this equation. Finally, the exponential function method and the G′/G-expansion method are employed to extract more solutions to this coupled system of equations. The parameter constraints are also given in order for the solutions to exist.
